TSB 95-09-05 Bronco Fiberglass Roof Seam Cracks

LIGHT TRUCK: 1991-1995 Bronco

ISSUE: Cosmetic cracks may appear in the seam sealer used on the exterior surface of the roof. This occurs because the original sealer was not flexible enough.

ACTION: Repair the fiberglass roof seam sealer cracks by using the following Service Procedure.

SERVICE PROCEDURE

1. Remove all the old sealer material from the seam about 25.4mm (1") beyond each end of the crack.
a. Scrape out the seam cavity.
b. Bevel the ends of the original sealer material that remains intact. Refer to Figure 1.
2. Roughen the sidewalls of the seam cavity with sandpaper. Blow out the area with clean compressed air.
NOTE: DO NOT USE ANY OTHER METHOD OF SANDING. ROOF REPAIR PAINT IS PRESENTLY NOT AVAILABLE.
3. Mask the area surrounding the repair with masking tape to prevent contact of the replacement sealer material with the roof painted surface.
4. Squeeze a sufficient amount of 3M Ultrapro Autobody Sealant (3M Part No. 08302) into a small container. Mix the appropriate color of Ford touch-up paint into the sealant material first, prior to application to the roof seam.
NOTE: PAINT WILL CRACK IF IT IS APPLIED ON TOP OF THE SEALANT AFTER THE REPAIR IS MADE.
5. Using a flexible poly blade:
a. Press the mixed material into the seam cavity.
b. Completely fill the cavity, leaving no voids.
c. Smooth the material to the same level as the original material.
6. Allow about 30 minutes for the sealant to cure.
7. Remove the masking tape.
